Mighty Thunderdart ★★★★

Taken all the way down to base materials, one Mighty Thunderdart is 2 crafting steps deep and needs 3 intermediates — Ancient Lumber ×3, Gold Ingot ×1 and Wolfram Ingot ×1 — which resolve to 10 distinct raw materials totalling 18 units, plus 19 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 740 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 8 Wind Cluster, 4 Lightning Cluster, 3 Fire Cluster and 2 other kinds.

The chain crosses three disciplines — Carpenter to Lv 50, Blacksmith to Lv 50 and Goldsmith to Lv 50 — so no single class can finish it unaided.

5 of the 10 raw materials come out of the ground, and 4 of them are time-gated: Ferberite (3:00), Gold Ore (9:00) and 2 others. The widest gap between consecutive opening times is 18 Eorzean hours, about 53 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
